Running lean, could be a MAF problem, O2 sensor problem.

P1151 is a definite 02 sensor problem. 171 and 174 could just be codes as a result from your 1151 problem. Replace your O2 sensors

Im not sure what the codes on but if your exhaust has the cats removed, the check engine light will always stay on unless u get another part to go in its place.

Everyone knows this so if u just read it u wasted five seconds of your life
